Quiz Grade Formula

The following formula is used to calculate a quiz grade.

G = CA / TQ × 100
  • Where G is the % grade
  • CA is the correct answers
  • TQ is the total number of questions

To calculate the quiz grade, divide the number of correct answers by the number of questions, then multiply by 100.

The illustrative plus/minus scale below uses the unrounded percentage. The simple scale instead uses A ≥90%, B ≥80%, C ≥70%, D ≥60%, and F below 60%; you can also choose no letter grade. Your instructor’s syllabus controls actual cutoffs and rounding. Tables support 1–1,000 questions; other modes support counts up to 1 billion.

LetterUnrounded percentage
A+97% through 100%
A93% to less than 97%
A−90% to less than 93%
B+87% to less than 90%
B83% to less than 87%
B−80% to less than 83%
C+77% to less than 80%
C73% to less than 77%
C−70% to less than 73%
D+67% to less than 70%
D63% to less than 67%
D−60% to less than 63%
